To all whom it may concern:

Be it known that I, MAx A. DoELoKNER, a citizen of the United States, resident of Louisville, in the county of Jefferson and State of Kentucky, have ,made a certain new and useful Invention in To-y Flying- 'Machines; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon,

which form a part of this specification.

Figure 1 is a side view of the invention. Fig. 2 is a detail plan view of the gearing showing the knocker.

Fig. 3 is a detail side view of the same, including the base.

Fig. 4 is a detail perspective View of the plane body.

Fig. 5 is a similarview of the cap.

Fig. 6 is a similar view of the tail fins.

Fig. 7 is a detail bottom plan .view of the upper plane.

Fig. 8 is a detail plan view of the lower plane showing thecarrying wheels.

The invention has relation to toys, having for its object to provide a toy having the form of an air shipof aeroplane type, capable of economical manufacture and assemblage, which is rotatable upon a fixed stem or axis, or revoluble around said axis, and which provides an attractive ornament and means of amusement.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings illustrating, the invention, the numeral 2 designates the aeroplane and, 3 the stationary base havlng a vertical fixed stem 4:, upon or around which the aeroplane rotates or revolves.

It is first necessary to devise asimple and practical manner of constructing the aeroplone' and to this end, the upper and lower planes 5 and 6 are each stamped from -a single piece of sheet .metal in completed form in. one stamping, each plane having seats 7 stamped therein without perforation of the metal, .said'seats adapted to receive the ends of the uprights or posts '8 connecting the planes together, said uprights being position, said 'motor bein weighted,

soldered at their ends in said seats, and the lower plane having a central transverse concave seat 9 formed thereln slmultaneou. ly

with the stamping, for the reception of the body 10 of the plane. This body is of conical form, the 'blank therefor being stamped in one operation to include a top opening 11, having an ornamental raised margin 11, said blank being bent around a suitable conical mandrel and being lapped at the edges and soldered at the lap. A circular rounded cap 12 is fitted to the open larger end of said body and completes the same, said cap being spun from a single plece of sheet .metal. .A spring motor 13 is inserted within said bodyprior to placing the cap in r suitably held against rotation wlthin the ody. A transverse'double horizontal tail fin 14 is stamped from a single piece of sheet metal, with a central longitudinal concavityl5 fitting over the tail of said body and soldered thereto, a single vertical fin 16 being soldered in position between the horizontal fins. A supporting spring 17 below the tail fins, and a gun 18 is secured in position in front of the opening of the body, which is desi ned for the accommodation of the pilot.

is soldered in positlon hewheels 19 are carried by aframe 20, which is soldered to the lower plane.

The motor includes the main spring 21, attachedat one end to the motor frame and having a gear train 22 driving the propeller shaft 23, said gear train also drivlng I a toothed wheel 24:, against which a spring knocker 25 has bearing, to simulate the exhaust 0f,an explosive engine in action. An

adjusting handle'device 25 is rotatable to press the-spring knocker away from the toothed wheel, through cam 26 of said deend bearings in the motor frame and passing through the center of and attached to the motor spring, said'stem having a lower thread 28 engaging a upper end of the stem 4; and to fac litate winding the spring, the base 3 which 1s upon a stationary stem 27, having threaded seat 29, at the vice, the knocker being then out of action and capable ofbeing brought into actlon as is dished, and stem 4 is1pr0- vided with a knurled handle 30, adapted to be grasped between thumb and finger, and located within the concavity of said base.

I claim 1. A toyflying machine having a station-.

end connection with said standard and at its other end being connected to said frame whereby the motor and body are rotated as the spring unwinds, a propeller having a shaft provided with a gear train connection with said spring and rotating simultaneously with the rotary movement of said body and motor, a toothed wheel driven by said gear train, and aknocker device engaging said toothed wheel, said standard having a winding handle for the spring located within the dished bottom of said base.

2. A toy flying machine having an upper plane stamped from a single sheet of metal and provided with spaced seats stamped therein, a lower plane similarly made and provided with a transverse concavity stamped centrally thereof, posts soldered at their ends within the seats of the upper and lower planes, a body ofconi-cal ,form made of a single piece of sheetmetal lapped at the joint, said body fitting and soldered in said transverse concavity, a horizontal body fin of double form having a longitudinal concavity fitting over and soldered to the pointed end of said body, a vertical tail fin attached centrally to said horizontal fin, a motor fitting in the larger end of said body,

and a cap piece for said open end spun from a single piece of sheet metal.

In testimony whereof I aflix my signature in presence of witnesses.

, MAX A. DOELCKNER.
